Favorable Trends in the Self-Storage Sector Self-storage has developed a favorable reputation as recession-resilient due to its diverse, defensive demand drivers. Household mobility is the main storage demand driver, which benefits in both economic expansions and contractions. A diversified tenant mix including residential, commercial, military and student users. Historically low maintenance cap ex requirements, absence of tenant improvement requirements and high yields also drive positive overall cash flow characteristics. Source: Green Street Advisors.

Favorable Trends in the Self-Storage Sector Industry supply growth has been muted by a challenging financing and operating environment in which small, private operators are struggling to compete. Total construction starts are down by approximately 65% from the levels seen four years ago. Source: Self Storage Data Services, Inc. and U-Store-It estimates (1) Includes alterations/renovations and interior completions (2) Overstates new supply by counting the full facility size for alternation/renovation projects Excluding alterations/renovations and secondary markets in which the REITs do not compete, SSDS reports just 7 new construction starts for the top 50 MSAs in the second quarter of 2010. Over the past four quarters, U-Store-It has had just 13 competing stores open across its 400-property portfolio, and only 9 of these properties compete within a U-Store-It facility’s primary 3-mile trade area. 0.0 1.0 2.0 3.0 4.0 5.0 6.0 0 10 20 30 40 50 60 70 80 90 1Q06 2Q06 3Q06 4Q06 1Q07 2Q07 3Q07 4Q07 1Q08 2Q08 3Q08 4Q08 1Q09 2Q09 3Q09 4Q09 1Q10 2Q10 Total New Square Footage (millions)2 Construction Starts1 New Supply # of Construction Starts Square Footage
